Answer .

Laboratory tests
You may have laboratory tests to decide out other issue that reason a few symptoms like those of Alzheimer's dementia, for example, a thyroid issue or vitamin B-12 insufficiency.
Brain-imaging tests
Alzheimer's dementia comes about because of the dynamic misfortune (degeneration) of brain cells. This degeneration may appear in an assortment of routes in brain filters.
Be that as it may, these outputs alone aren't sufficient to make a determination. Sweeps aren't utilized to diagnose the condition on the grounds that there is cover in what doctors consider ordinary age-related change in the brain and strange change.
Be that as it may, brain imaging can help:
Preclude other causes, for example, hemorrhages, brain tumors or strokes
Recognize distinctive kinds of degenerative brain malady
Set up a gauge about the level of degeneration
The brain-imaging advancements frequently utilized are:
Magnetic resonance imaging (MRI). A MRI utilizes intense radio waves and magnets to make a definite perspective of your brain.
Computerized tomography (CT). A CT check utilizes X-beams to acquire cross-sectional pictures of your brain.
Positron emission tomography (PET). A PET sweep utilizes a radioactive substance known as a tracer to identify substances in the body. There are distinctive kinds of PET sweeps. The most generally utilized PET output is a fluorodeoxyglucose (FDG) PET sweep, which can distinguish brain areas with diminished glucose digestion. The example of digestion change can recognize diverse sorts of degenerative brain ailment.
PET outputs have as of late been produced that identify bunches of amyloid proteins (plaques), which are related with Alzheimer's dementia, however this kind of PET sweep is normally utilized as a part of the exploration setting.
2. Cerebrovascular dementia
Lab tests
On the off chance that your therapeutic record does exclude late qualities for key pointers of the wellbeing of your heart and blood vessels, your doctor will test your:

Brain-imaging strategies your doctor may prescribe to help diagnose vascular dementia include:
Computerized tomography (CT) filter. For a CT examine, you'll lie on a restricted table that slides into a little chamber. X-beams go through your body from different points, and a PC utilizes this data to make itemized cross-sectional pictures (cuts) of your brain. This test is effortless and takes around 20 minutes.
A CT output can give data about your brain's structure; tell whether any locales demonstrate shrinkage; and identify confirmation of strokes, scaled down strokes (transient ischemic assaults), blood vessel changes or tumors. Here and there you'll get an intravenous (IV) infusion of a difference specialist that will help feature certain brain tissues.
Magnetic resonance imaging (MRI). A MRI utilizes radio waves and a solid magnetic field to deliver itemized pictures of your brain. You lie on a tight table that slides into a tube-formed MRI machine, which makes noisy slamming commotions while it produces pictures.
The whole system can take a hour or more. X-rays are effortless, however a few people feel claustrophobic inside the machine and are bothered by the commotion. X-rays can give considerably more detail than CT filters about strokes, smaller than normal strokes and blood vessel variations from the norm.
Carotid ultrasound
This system utilizes high-recurrence sound waves to decide if your carotid conduits — which keep running up through either side of your neck to supply blood to brain — hint at narrowing because of plaque stores or basic problems. Your test may incorporate a Doppler ultrasound, which demonstrates the development of blood through your supply routes notwithstanding auxiliary highlights.

* Difference bwtween alzheimer and cerebrovascular dementia
Cognitions
Vascular: Cognitive capacities regularly appear to decrease all the more all of a sudden identified with an occasion like a stroke or a transient ischemic attack (TIA) and afterward stay more steady for a period. These progressions are frequently portrayed as step-prefer since in the middle of them, brain working may hold consistent.
Alzheimer's: While insight can change to some degree in Alzheimer's, the individual's capacity to think and utilize his memory step by step decays after some time. There isn't generally a sudden, critical change starting with one day then onto the next.
Rather than the progression like decrease in vascular dementia, Alzheimer's is commonly more like a slight, downward slope of a street after some time.
Walking and Physical Movement

Both the cognitive and physical debilitations identified with vascular dementia ordinarily create in the meantime since they are regularly the aftereffect of a sudden condition like a stroke.
Alzheimer's: Often, mental capacities like memory or judgment decay at first, and afterward as Alzheimer's advances into the center stages, physical capacities like balance or walking demonstrate some crumbling.
* Difference between alzheimer and depression

May have symptoms of depression that are less extreme
May encounter scenes of depression that don't keep going as long or return as often
Appear to be less inclined to discuss suicide and endeavor suicide less frequently
